    <p>
      This sample demostrates the use of the ZoomSlider extension.
      When using the ZoomSlider extension, the diagram Div must always be a direct child
      of a Div using <code>position: relative</code> or <code>position: absolute</code>,
      so that the ZoomSlider HTML DOM can be positioned correctly relative to the Diagram Div.
  </div>

  <script type="module" id="code">
    import * as go from "../release/go-module.js";
    import { ZoomSlider } from './ZoomSlider.js';

    if (window.goSamples) goSamples(); // init for the samples -- you don't need to call this
    const $ = go.GraphObject.make; // for conciseness in defining templates

    const myDiagram =
      $(go.Diagram, 'myDiagramDiv', // create a Diagram for the DIV HTML element
        {
          'undoManager.isEnabled': true // enable undo & redo
        });

    // define a simple Node template
    myDiagram.nodeTemplate =
      $(go.Node, 'Auto', // the Shape will go around the TextBlock
        $(go.Shape, 'RoundedRectangle',
          { strokeWidth: 0, fill: 'white' },
          // Shape.fill is bound to Node.data.color
          new go.Binding('fill', 'color')),
        $(go.TextBlock,
          { margin: 8 }, // some room around the text
          // TextBlock.text is bound to Node.data.key
          new go.Binding('text', 'key'))
      );

    // but use the default Link template, by not setting Diagram.linkTemplate

    // create the model data that will be represented by Nodes and Links
    myDiagram.model = new go.GraphLinksModel([
      { key: 'Alpha', color: 'lightblue' },
      { key: 'Beta', color: 'orange' },
      { key: 'Gamma', color: 'lightgreen' },

    ], [

      { from: 'Beta', to: 'Beta' },
      { from: 'Gamma', to: 'Delta' },
      { from: 'Delta', to: 'Alpha' }
